7 0 all whom it may concern:

Be it known that I, WILLIAM A. TAYLOR, a citizen of the United States, residing at Detroit, in the county of l/Vayne and State of Michigan, have invented a new and use ful Automobile Alarm, of which the following is a specification.

This invention relates to a burglar alarm or attachment to be placed on the wheel of an automobile, one of the objects of the invention being :to provide a device of this character which, when movingwith the wheel will, when properly set, sound an alarm so as to attract attention.

Another object is to provide a burglar alarm of this character which canv be easily adjusted into or out of active position Without removing'it from the wheel provided the owner has a key giving him access to the interior of the structure to enable him to make the necessary adjustment.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is an elevation of a portion of a vehicle wheel, showing the lock applied thereto.

Figure 2 is a section on line 2-2, Figure 1.

Figure 8 is an elevation of the clappers and their supporting arms.

Figure t is a plan view of the lock.

Figure 5 is an enlarged section on line 5-5, showingthe clappers and their supporting means housed in inactive positions.

Referring to the figures by characters of reference 1 designates a segmental hollow bell structure adapted to lap two or more spokes of a wheel W. Extending laterally from one face of this structure is a hollow segmental section 2 adapted to be inserted laterally between two of the spokes. It is preferred to have the bell structure upon the inner side of the wheel. The outer side of the segment 2 has an opening 3 therein normally closed by a door 4. provided with a suitable lock whereby the door can be fastened 1n shut position and it is impos- 1sible to open it without the use of a proper rey. Y M

Mounted. on the inner surface of the door a is a box or housing 5 having a door 6 and secured within this housing or box is one end of a lazytongs 7 the other end of which has a disk 8 attachedathereto. A lug 9 extends from the center of this disk and constitutesa bearing for a strip 10 which is ogee curved so as to provide oppositely curved arms. Pivotally attached to the free end of each of these arms is alink 11 which, in turn, is loosely connected at 12 to a short rod 13 having a ball or enlargement 14 at its free end forming a clapper.

The segmental section 2 is held in place preferably by a screw 15 extending through the rim of the wheel and into an opening 16 in the top of said section. Thus the alarm cannot be removed without first removing the tire. In addition to this fastening means screws may be directed into the rim from within the housing 1 through additional openings 17 suitabl located in the sections 2. Thus even though the tire should be removed and the screw 15 disengaged from the alarm, the said alarm would still be held in place by the supplemental screws.

After the alarm has been secured to the wheel it remains a permanent fixture thereon Without detracting to an objectionable extent from the appearance of the wheel. To set the alarm the user opens the door 4, thus getting access to the door 6 which is also open. With the door 4: partially opened the lazytongs 7 are extended so as to project from the section 2 into the housing 1 after which door 4: is completel closed and locked and the clappers 14 will e suspended within the housing 1. It will be apparent that when the wheel is rotated the clappers 14 will successively strike the walls of the housing 1 and asthese walls are made of a resonant material the noise produced will serve to attract attention to the vehicle. Thus the danger of theft of the vehicle to which the alarm is attached is reduced to the minimum.

When it is not desired to use the alarm the door 4: can be opened, the lazytongs pulled back into the box 5 and the cover 6 moved to shut position.

It is to be understood that when the door or cover 6 is shut the arms of the strip 10 will project from the top and bottom of the box 5 as shown in Figure 5.

What is claimed is 1. An alarm comprising a resonant housing, a segmental section extending laterally therefrom for insertion between the spokes of a wheel, a door movably connected to said section, a clapper, and means for supporting the clapper either within the housing in active position or within the extension in inactive position.

2. An alarm comprisinga resonant housing, a segmental section extending laterally therefrom for insertion between the spokes of a wheel, a door movably'conneoted to said section, a clapper, and an extensible connection between the clapper and the door for supporting the clapper either within the housing in active position or within the extension in inactive position, and means upon the door for fastening the clapper in inactive position.

3. An alarm including a resonant housing, a segmental section thereon lnsertible between spokes of a wheel, a door normally closing said section, an extensible support upon the door, a strip mounted to rotate freely on the support, clappers loosely conneoted to the ends of the strip for striking the housing when the support is extended, and meansforholding the support retracted into the extension.

4:. An alarm including a resonant housing, an extension thereon having an open ing, a door normally closing the opening, an extensible foldable support mounted upon the door, olappers, a connection between the clappers revoluble on the support,.and means for holding the support retracted with the clappers in the extension.

In testimonythat I claim the foregoing as my own, I have hereto affixed my signature 1n the presence of two wltnesses.
